The Diamondhead AR-15 5.56 NATO T-Brake Muzzle Compensator is an excellent upgrade to get better control during sustained fire and also to lessen perceived recoil increasing accuracy. Manufactured from 4140 hardened steel, the T-Brake's unique shape significantly reduces muzzle climb and felt recoil. The T-Brake's styling complements the Diamondhead VRS-T hand guard but it can be used with any 5.56mm barrel.
